Product Overview
Model: EK-3020
- Adjustable Alarm Deviation: The alarm deviation for over-temperature is adjustable within 0~50, satisfying diverse user needs.
- Proportional On/Off Control: In the event of sensor failure, the controller controls the compressor to start and stop proportionally, effectively eliminating the risk of temperature runaway caused by sensor malfunction.
- Adjustable Alarm Delay: The temperature alarm delay can be set from 0 to 99 minutes after power-on, effectively avoiding false alarms caused by elevated initial temperature during first power-up.
- Upper & Lower Limit Setting for Temperature Control Points: Separate parameter settings for users and administrators, with configurable upper/lower limits for user-adjustable parameters. This prevents cargo loss from incorrect parameter settings due to accidental operation, making the system more intuitive and user-friendly.
